Instructions and Scoring. Please read carefully before you begin. Check (þ) each item as you read it (1 pt. each). ¨
Do not discuss this
test with anyone except Mr. Hansen until the answers are posted on the Web.
There are a number of students who may be taking make-up tests. ¨
There will be a
1-point deduction for each unnecessary disturbance during the test: speaking
out of turn, asking a question that has already been answered, etc. If you
have a question, please raise your hand and keep working until I spot you.
This may take a minute. Please do not call out my name, since that creates
unnecessary noise. If you see a typographical error, please mark it clearly
for extra credit. If you finish early, please leave quietly and
unobtrusively. ¨
No calculator
is permitted. ¨
There is no
partial credit for the multiple-choice questions. ¨
This portion is
worth 50 points. Tomorrow’s portion is also worth 50 points. The higher of
the two will be doubled. |
|
|
Part I: Always, Sometimes, Never. Write A, S, or N depending on whether the statement
is always true, sometimes true, or never true. Each question is worth 4 points.
Partial credit in the event of wrong answers is possible if you provide a
worthy diagram or short explanation of your thinking. |
